Applicationfled December 12, 1914. Serial No. 876,829.

To all whom t may concern.' f

Beit known that I, PHILIP MALcAMr, a citizenof the Republic of France, and a. resident of New Orleans, in the parish of Or leans and State of Louisiana, have invented a new and useful Improvement in Lamps, of which the following is a specification.

My invention is an improvement in lamps, and has for its object to provide a lamp of the character specified, adapted for` burning liquid fuel, as for instance, kerosene, and so arranged that it may be used for lighting, heating and cooking, and wherein means is provided for regulating the combustion of the fuel to produce the results desired.

In the drawings: Figure 1 is a vertical section of the improved lamp, Fig. 2 isa tcp plan view of the burner portion of the lamp,

and Figs. 3 and 4 are sections on the lines 3-3 and 4 4, respectively,of Fig. 2.

rlhe present embodiment ofthe invention comprises a base consisting of a tank or resl ervoir 1, for containing fuel, and having a central draft tube 2,' the wick 3 being of cylindrical form and encircling theV Vtube.`

rlhe tank has a'nipple 4, which encircles the draft tube and is held coaxial therewith, and the tankor reservoir is supported by legs.

A. plate 6 is arranged diainetrically ofthe draft tube at the bottomthereof, the plate having a central opening and a frusto-conical guide 7 is seated on the plate at thecenter thereof, the small lower end of the guide registering with the central opening The guide has a marginal on the upper face of the plate.

A rod 9 is mounted tokslide vertically through the opening of the plate andthe lower end of the rod rests upon the inner end of a lever 10, whose outer'en'd is provided with a weight 11." The lever is pivotally mounted, having a transverse pin 12, near its outer end, and the pin is received in notches in arms 13, extending outwardly from a bracket plate 14. The bracket plate is curved transversely and the upper end` thereof is secured to a ring 15, which encircles the tank or reservoir, and is connected thereto in any suitable or desired manner.

An angle plate has one of its portions secured to the outer face ofthe bracket 14, and the other portion of the angle plate eX- tends laterally outward from the bracket l and has an opening through which'is threaded a set screw 17, the lower end ofthe set speeiacanon of Letters raient.

screw engaging the lever 10 on the outer side of its pivotal connection. The angle plate provides a stop or an abutment through which the set screw is threaded to Acause the screw to move longitudinally when therod above and below the hood to hold it in adjusted position. The hood is a circular plate or disk of conical form. and is provided with a radial notch or recess 20.

A ring 21 is arranged below the hood, the

ring being supported by screw bolts 22, which pass downwardly through the yhood and through the ring and are engaged by nuts 23, below the ring, and the ring is iprovided with Y. an upwardly extending marginal flange 24 at its inner edge. This flange has an annulargroove on its inner face at its top, and a cylindrical damper 25 is held by the ring. rlhe damper is provided with an annular groove at its upperV end forming an external rib which engages within the groove of the flange of the ring, thus supportingthe damper, and at its lower end the damper is provided with a Vmarginal outwardly extending flange 26. The damper and the ring are both coaxialwith the rod, and the lower end of the damperjfits within a sleeve 27, having` its upper end 'curved inwardly as indicated at 28.

rllhereisv a Vspace between the adjacent edges of the flanges 26 and 28, and when these flanges are in the same plane this annular opening or space is at its smallest eX- tent. l/Vhen the'damper 25 is Vloweredthe space is increased. as will 'be evident from an inspection of Fig. l.; rlhe opening or recess 20 i'nthe hood18 may be closed by means of a.` plate 29, the said plate being held in position to cover the opening 20, by means of'one of the screw bolts 22. Y

'Itwill be noted from an inspection of Figs. 1, 2 and 4 that the edges of theplate which holds the plate, the plate may beV` firmly secured in the opening. To move the plate it willf be` necessary to loosenltlie nut 23 in( order that the plate may swingout of the opening. y

The wick is raised or lowered in theusual manner, by-mechanism connected with the l shaft 30, the inner end of the shaft extending through an openingin thev tank or reser-k voir, and being supported in a tube or sleeve 31, outside of the tank.

' Y Avided with a wheel -32 at its outer end for convenience in turning, the same, and the sleeve'is provided with an` arm 33, adjacent tothe wheel. fitting around the sleeve and clamped there- 'oncby means'offascrew 35.` The free end of the arm extendsA beyond the periphery of 'the wheel,-and the outer corner of the arm adjacentto the tank or reservoir is beveled as shown more particularly in Fig. 3. An

l arm 36 isv secured diametrically of the wheel,

and alt onevend the arm extends beyond the whee'land is pointed. The arrangement of the arms 33 and 36 is such with respect to Vthe wick and its operating mechanism, that Vwhen the upper end of the wick is iiush with the upper endl of the draft tube and the nipple 4, the point of the, arm 36 will be arrangedv below the screen 37;

-in registerwith the point of the arm A. screen 37 1s arranged transversely ofY the sleeve 27'at its lower end, and a sleeve 38 is connected with the screen. rIhe screen k 37 isa plate, having circular openings, and

ase'eond screen 39 of-pe'rforate material is y A plateV 40 is V'arramged transverselyof the lower end of thedamper 25, the, said'plate having an Yopening through which the rodf9 passes. The rodalso passes through a central opening` inthe screen 37 and through a. guide 41V yin thesleeve 38. The guide is connected to` the Vscreen 3,9 as shown in Fig.- 1, and the l sleeve 38 f: has llongitudinallyv kextending recesses 42, through which the connections be-I Avthe/door also having `openings covered Vby -isinglass or Vthe like, and permitting access to theinterior of the chimney. At its vlower end the chimney. rests upon supports 50, to

'Standards 51 extend upwardly from the tank.` or Ureservoir, `and the saidstandards support ai ring 52 at their tops. The standards are offset outwardly intermediate their formV is arranged above` thechimney and b ejlow thering 52, .and the said tank has an annular cover 55vprovided with a handle 56, extending radially therefrom. The tankl or reservoir54; isv also provided withA a dis- The shaft is pro-` The arm has a bearing 34 charge valve 57 and with a handle 58 for convenience in placing or removing the same. The sleeve 59 that forms the interior of the tank is flanged outwardly at its lower end as indicated at 60, and this flange rests upon the outwardly flanged upper end 61 of the chimney. This sleeve 59 is open at its upper end, and an annular or ring-shaped cover G2 is provided for the said end. The cover has a depending flange 63, which fits within the sleeve, andthe outer edge of the cover proper rests upon the inner edge of the cover 55 for the tank or reservoir 54. Each ofthe supports 50 as shown in Fig. 2, is formed from a strip of suitable material, having a notch in one side edge and at the center of the strip. The strip is then doubled upon itself, and the ends are bent outwardly away from each other. rlhe bent Vout ends are secured to the top of the tank smooth and even with the upper edge of the nipple 4. The arms or indicators 33 and 36-should be in alinement, when the upper end of the wick is n1n the position noted, and

after these things lhave been attended to the chimney or ltube 45 is placed on the supports 50. The tank or reservoir 54 is now placed and centered on the upper end ofv the tube 45. The standards 51 form a guide for the proper placing of this tank. The said tank is designed to receive water, and it should be filled before the wick is lighted. The cover 55 isplaced on the tank,

and with the left hand the operator presses downwardly on the weight 11, thus swinging the lever 10 as indicated invfull lines in Fig. 1. VViththe right hand the operator turns the set screw 17 until the lever is fixed in the full line position of Fig. 1. The pressing down of the outer end of the lever raises the inner end, thus lifting the rod and parts connected therewith. The door 49 is now opened and the wickis raised slightly until the arm 36 is abouty one-half inch in advance of the arm 33. The wick is now lighted and the door is closed. The wick is permitted to burnv for a while to heat the damper, orl at least until it is burning with av White iame throughout its area. When this state of'aifairs obtains, the set screw 17 is turned .in the opposite direction, that is, in a direction to release the outer end of the lever 10, and permit the inner end of the lever-to ,be moved downwardly by its own weight and that of connected parts. As soon asthe inner end' of the lever begins to descend the white flame begins to change to blue, and with every turn of the set screw the blue increases. This operation is continued until the proper color of flame is secured. It will occasionally happen that in changing the size of the flame a buzzing or vibrating noise will result. In order to stop this noise the set screw 1 7 is turned in a direction to lower the damper 18. Whenever it is desired to increaseV the height of the flame the Vset screw 17 is turned in a direction to swing the outer end of the lever downward and to raise the damper 18. When it is desired to i decrease the size of the flame the` set screw is turned in the opposite direction. In order to extinguish the flame, the wheel 32 is turned until the arms 33and 36 are in register and the damper 18 is lowered juntil it rests upon the upper end of the wick, ex-` tinguishing the flame.

The improved stove may be used for boil- It will be noted from an inspection of Fig. Y

al, that the ring 21 is provided at its periphery on its under face with an annular groove 21, the said groove being directly above the wick of the lamp. This is an essential feature, for when the damper is lowered far enough that portion of the ring at the groove will immediately extinguish the ame. As is known,'when a wick is smooth and even and uniform it will produce a uniform flame. It is also known that when a wick is disturbed by attempts to raise or lower the same, it will become uneven and an irregular flame will necessarily result. The lamp may be used as a night lamp by moving the cover plate 29, that is, by opening the said plate and covering the remainder of the wick with the ring 21. When the plate 29 is moved to uncover' the opening with the ring resting just above the wick only that portion of the wick at the opening 20 will be ignited, thus the lamp can be arranged to provide for a pilot burner, lighted and ready to ignite the remainder of the wick as soon as the ring is lifted. With one burner the improved stove can be used to cook simulta neously two or more articles, merely by placing one pan above the other and the griddle at the top.

It will be evident that with the improved stove a white orreading light may be obtained, or a blue flame for cooking. In addition the lamp may be used as a night lamp and as many cooking vessels may be arranged above as there is room for without increasing the amount of fuel used.
